The Virus is a type of malware that can be embedded in the code of other applications and reproduced; besides, viruses copy themselves and spread over the network. A computer virus is created in order to reduce the functionality of the hardware and software structures of devices: delete files, damage data, block the user's work. The impact of infections can be not only of destructive character, but also annoying, as they slow down the operation of the operating system, lead to crashes and sudden reboots, and reduce free memory space.

Computer viruses actively use the CMD and Powershell features, generate scripts on their own, and make changes to the operating system registry.

The impact of viruses on the information structure of companies is destructive and leads to economic losses, leakage of financial assets, personal data, and commercial confidentiality.
